Answer:

a. 65:195

b. A

Step-by-step explanation:

for part a:  

1:3 means there are 1+3=4 parts

so 260/4=65

so the 1 is 65 and the 3 is 3(65)=195 so

a. 65:195

for part a.

3:5 is equal to 1:n

Answer:

see explanation

Step-by-step explanation:

(a) Add the parts of the ratio, 1 + 3 = 4 parts

Divide 260 by 4 to find the value of one part of the ratio.

260 ÷ 4 = 65 ← value of 1 part of the ratio, thus

3 parts = 3 × 65 = 195

260 in the ratio 1 : 3 = 65 : 195

(b)

Given

3 : 5 ← divide both parts of the ratio by 3

\frac{3}{3} : \frac{5}{3} = 1 : \frac{5}{3} → A

<h3>What is an integer exponent?</h3>

In mathematics, integer exponents are exponents that should be integers. It may be a positive or negative number. In this situation, the positive integer exponents determine the number of times the base number should be multiplied by itself.

It is given that:

The expression:

= \rm (\dfrac{x^4a^2b^3}{x^{-2}ab^2})^3

After using the integer exponent property:

\rm =\dfrac{x^{12}a^6b^9x^6}{a^3b^6}

= a³b³x¹⁸ Or

=x¹⁸a³b³

Thus, the simplification form of the provided expression is x¹⁸a³b³ option

(d) x¹⁸a³b³ is correct.
